In this picture that flash im using is actually about 35 years old and it works like a charm.. sure its full manual but its pretty powerful and im starting to get the hang of it.. I have shoot full manual with it and instead of compensating the flash i have to adjust my aperture accordingly and also shoot in flash WB there i can also adjust the brightness ect. I just shoot it anywhere with the shutter speed depending on the lighting. Its fun to you use once you get the hang of it.. i love bouncing it off the ceiling wall ect. its so much fun and gives great results.
